INVENTOR" United. States Patent 2,792,581 PAINTBRUSH EXTENSION HANDLEThomas M. Woyton, ElmonhN. Y. Application November 9, 1955, Serial No.545,821 1 Claim. (c1. 15-144 This invention relates to a novel extensionhandle for paintbrushes and has for its primary object to provide novelmeans for detachably securing the handle of a paintbrush to an end ofthe extension handle and so that the axis of the paintbrush may bedisposed at any desired angle relative to the axis of the extensionhandle most convenient to the user.

A further object of the invention is to provide an extension handlehaving a securing means for detachably securing the handle of apaintbrush thereto and whereby through the simple operation oftightening one fastening the paintbrush is secured to the extensionhandle at a desired angle relative thereto.

A further object of the invention is to provide an extension handlethrough the use of which the necessity of moving ladders and seafloldswill be minimized; which will minimize the risk of a painter falling;and which will afiord a firm grip to the user enabling the paintbrush tobe held. steady by the extension handle during execution of a paintingstroke.

Various other objects and advantages of the invention will hereinafterbecome more fully apparent from the following description of thedrawing, illustrating a presently preferred embodiment thereof, andwherein:

Figure l is a fragmentary side elevational view showing the extensionhandle with a conventional paintbrush secured thereto;

Figure 2 is an enlarged sectional view taken substantially along a planeas indicated by the line 22 of Figure 1;

Figure 3 is an enlarged sectional view taken substantially along a planeas indicated by the line 3-3 of Figure l, and

Figure 4 is a cross sectional view through the grip portion of theextension handle.

Referring more specifically to the drawing, the extension handle,designated generally 6 and comprising the invention, includes anelongated handle member, designated generally 7, and a clamping unit,designated generally 8. The handle 7 may be formed of any suitablerelatively lightweight material of suflicient rigidity, such as certainrelativel lightweight woods or aluminum. The handle member 7 includes anelongated intermediate portion 9 which may be of various lengths and ofvarious cross sectional shapes and which is preferably relativelyslender as compared to the end portions 10 and 11 of the handle member7. The end portion 10 constitutes the head or upper end of the handlemember and is laterally enlarged and has substantially fiat oppositesides 10a and 10b which are disposed substantially parallel to oneanother. The head 10 has a bore or opening 12 extending therethroughwhich opens outwardly of said sides 10a and 10b and which is disposed insubstantially a central position relative to the head. The other end 11constitutes the handgrip of the extension handle 7 and is preferablywidened somewhat relative to the intermediate portion 9 and likewise hassubstantially fiat opposite sides 11a and 11b which are disposedsubstantially parallel to the sides 10a and 10b. The handgrip 11 is alsoprovided ice 2 away from the plane of the head 10 and is provided with,

an outwardly opening notch 19, as best seen in" Figure l. The clampsection 15 includes apart 20 forming a restricted, substantiallycoplanar integral extension of the other end of the plate 17 and whichhas an outturnedend portion forming a wall 21 which extends in adirection.

away from the head 10' and which is provided with an opening 22.

The other section 16 of the clamp 14 comprises an elongated metal bar orstrip hich is longitudinally bowed and which strip 16 has restrictedends forming tongues 23 and 2 which are reversely curved relative to theintermediate portion of the strip 16. The plate portion 17 of the clampsection 15 has an opening 25 which. registers with the bore 12 and thestrip 16 is provided with an opening 26 which is located more remotefrom the tongue 23 than from the tongue 24. The tongue 24 extendsloosely through the opening 22 for connecting the clamp sections 15 and16. Said clamp sections areadditionally connected by a long bolt 27which. extends through the openings the clamp section 16 and which isspaced therefromby a washer 29 and a split spring 29 is disposed next tothe bolt head 28 and the spring washer 30 is disposed between the washer29 and the clamping section 16. A wing nut 31 engages the threadedopposite end of the bolt 27 and a washer 32 is disposed between saidwing nut and the side 10b of the head 10.

When the extension handle 6 is not in use and the nut 31 is tightened,the tongue 23 will fit in the notch 19. By loosening the nut 31, theclamp section 16 can be swung away from the clamp section 15, said clampsection 16 pivoting relative to the clamp section 15 by engagement ofits tongue 24 in the opening 22, so that its tongue 23 swings outwardlyand away from the notch 19. In this manner, the portion of the clampsection 16 disposed between the tongue 23 and its opening 26 can bedisplaced sufficiently away from the plate 17 so that a portion of thehandle 33 of a conventional paintbrush 34 can be inserted between saidpart of the clamp section 16 and the part of the plate 17, which islocated between the opening 25 and its extended end 18, as illustratedin Figures 1 to 3. It will be noted that portions of the clamp section16, located adjacent the opening 26 and adjacent the tongue 23, aredisposed nearer the plate 17 than the part of the clamp section 16 whichis disposed between said portions, so that the brush handle 33 will beconfined immovably in the clamp 14 when the nut 31 is again tightenedfor drawing the clamp section 16 toward the clamp section 15. It willalso be apparent that the clamp sections 15 and 16 as a unit arerotatably mounted on the bolt 27. Thus, before the nut 31 is tightenedand after the brush handle 33 is in its position of Figures 1 to 3, saidclamp sections may be rotated relative to the head 10, with thepaintbrush 34, to position the axis of the paintbrush at any desiredangle relative to the axis of the extension handle 7. By then tighteningthe nut 31 the brush handle 33 is clamped in the clamp 14 and at thesame time said clamp is clamped immovably to the head 10 at the desiredangle. Thus, by a single operation of tightening the nut 31 thepaintbrush is not only secured to the extension handle but is locatedwith its axis at a Patented May 21 1957."

26 and 25- and through the bore 12 g and which has a head 28: disposedon the outer side of washer 30; The washer desired angle relative to theaxis of the extension handle for most convenient use. It will beapparent that the clamp 14 and the brush 34 are turnably adjustableabout the bolt 27 in either direction as indicated by the arrows 35 andin a planeparallel to the plane of the head 10.

The grip portionll is grasped with either'hand, with An extension handlefor paintbrushes comprising an.

elongated-slenderextension handle member having an enlarged end forminga head provided with substantially a pair of elongated clamp sectionshaving substantially aligned openings, a bolt extending through saidopenings and through the head bore for swivelly mounting the clampsections on one side of said head, a first one of said clamp sectionshaving an elongated flat portion extending to adjacent the ends thereofand having a side disposed against one side of the head, said clampsection having an outturned end, spaced from the bolt receiving opening,forming a wall provided with an opening, the other end of said clampsection being extended outwardly and having a centrally disposedoutwardly opening notch, said extended end portion being spaced asubstantial distance from the bolt opening, and the flat portion,disposed between the bolt opening and said extended portion, forming thejaw of said first clamp section; said other second clamp sectioncomprising an elongated strip said strip than the other tongue, saidother tongue engaging in said notch in one position of the clampingunit, said strip including an elongated portion disposed between thebolt opening thereof and said other tongue and which is outwardly bowedrelative to the fiat portion of said first clamp section, said othertongue forming a reversely curved extension of an outer end of saidoutwardly bowed portion and combining therewith to form the jaw of saidsecond clamp section, said second clamp section pivoting about the.engagement of said first mentioned tongue thereof in the wall openingfor swinging movement relative to the bolt toward and away from thefirst clamp section and being swingable outwardly to position the jawsin an open position to receive a part of a paintbrush handletherebetween, and a nut engaging said bolt for swinging the jaw of saidsecond clamp section toward the jaw of the first clamp section when thenut is tightened to clamp the handle in said jaws and crosswise oftheclamping unit, said clamping unit being clamped to the head by thetightening of the nut to position the axis of the brush handle at anydesired angle to the axis ofthe extension handle member.
